Hi Torsten,
=20
The ethtool stats you attached does not appear to be from the Intel =
driver. Are you sure your problem is with the Intel NIC?
=20
Thanks,
Emil

Thanks Emil for your answer.

I am  not using a "complete" server from Intel, but our local =
hardware-vendor has made the server. Using a SE7320VP2-mainboard and and =
SR4200-chassis. I now have tried the drivers 7.4.35, 7.3.20 and 7.0.41. =
The old kernel 2.6.16 is working fine with driver 7.0.41 -- the new =
kernel 2.6.20 is working for a few hrs before the intel-nic stops =
responding, regardless of the driver version.=20
I also tried to look into the kernel-configuration but using a =
distribution (Fedora Core 5) there are changes and kernel-patches where =
I am just lost.=20
The only interesting thing I found (and attached) is the output from =
"ethtool -S" while the problem exists. What does the value =
"tx_mac_pause" mean ??

Thanks for your help,


              Torsten.

		I tried to update our Kernel to 2.6.20 using the 2.6.20-1.2307.fc5smp
		from Fedora. I also updated the driver e1000 to Version 7.4.35-NAPI.
		   =20

	Have you tried drivers older than 7.4.35 (7.4.27, 7.3.20 etc)? You can
	get them from e1000.sf.net. It could be a regression problem.
=09
	 =20

		No other changes to hardware, hubs etc have been done. After some 1-2
		hrs uptime the Intel Nic just stops responding. I can ping through the
		Marvell NIC, but not the Intel Nic. The machine does not crash, so
		local log-ons are still working. I viewed information from "dmesg",
		"ifconfig" and "ethtool", but without any hint about a problem (at
		least from what I know).
		   =20

	When it stops working check out stats using ethtool -S and send us the
	output.
=09
	 =20

		The resolution so far was re-boot and using the 2.6.16 kernel again,
		   =20

	Have you tried looking at differences between the configurations in the
	kernel config?
=09
	 =20

		but I would like to ask the everyone if one could give me a hint about
		troubleshooting or even a solution.

	We'll try.
